When invoking the MessageViewController in Zendesk iOS SDK,We had som problems: It seems that messagingViewController can’t support Keybord “Chinese Traditional Zhuyin” on iPhone

I present MessagingViewController with the function below
func show(rootViewController: UIViewController?) {
guard let messagingViewController = Zendesk.instance?.messaging?.messagingViewController() else { return }
self.configureGlobalNavibarStyle();
let navi = UINavigationController(rootViewController: messagingViewController);
rootViewController.present(navi, animated: true, completion: nil)
print("\(self.TAG) - show")
}
Now,We can’t input Chinese Word with Keyboard “Chinese,Traditional Zhuyin”.
When we typed with keyboard “Chinese,Traditional Zhuyin”, only the letter could be input ,but we expect we can spell Chinese Word and Input.
